| Abstract: | A continuum model is adopted to study the macrosegregation phenomena during solidification of large steel ingots. Evolution
of temperature, melt velocity, and compositional concentration field during a 22 t steel ingot solidification are illustrated
by using the finite volume method. Numerical results of temperature distribution are validated by experiments. The influence
of local permeability relates to the friction that the melt experienced in mushy region is investigated. It is shown that
the continuum model is able to predict the temperature field, and the variation of permeability obviously affects the melt
flowing behavior and the final compositional distribution. |
